The substantially larger genome of Physarum polycephalum (estimated to be ∼300 Mb; Mohberg and Rusch 1971) could potentially harbor a substantially higher number of genes, but thus far there is no indication this is so (Baekmann and Sauer 1982). NIH Hideo Nomura. The exon–intron organization of its genes, examined in this paper, exhibits features apparently unique to this organism, features typical for the evolutionarily old (and usually small-genomed) taxa, as well as those characteristic for the more advanced (and large-genomed) ones.
